WHIP ROLL FOR LOOIVIS.

Application filed February 9, 1921. Serial No. 443,55.

T 0 all whom it may concern Be it known that I, VILLIAM B. VVIL- LIAMS, a citizen of the United States of America, and a resident of Greenville, county of Greenville, and State of South Carolina, have invented certain new and useful Improvements in Whip Rolls for Looms, of which the following is a full and clear specification. I

The object of this invention is to provlde an improved bearing or journal for the rockshaft of whip-rolls, and it consists of certain novel features hereinafter described and claimed.

In the drawing Fig. 1 is a perspective view of one of the bearings of a whip-roll rock-shaft;

Fig. 2 is a side view of the plural-bearin bracket now in common use;

Fig. 3 is a vertical longitudinal section through my improved bearing, shown in Fig. 1.

In the drawing, 5 designates the usual rock-shaft carrying the usual whip-roll-arm 6 provided with the usual notch-like bearings 7 for the whip-roll rod or roller. The shaft 5 extends through the circular journal hole in a wood block 8 which is fastened to the usual journal bracket 9 by means of a screwlO. This wooden block is desirably impregnated with oil or an oily substance so that oiling of this journal is unnecessary, thereby doing away with the use of a liquid oil, which, even with the utmost care, finds its way to the warp threads of the fabric and thus materially reduces its quality. With my bearing, I have found in actual practice that I not only provide ample lubrication for the shaft, rendering its operation entirely noiseless and practically without wear of the shaft or the bearingblock, but also that I avoid entirely the creation of the fine oily particles that the bearings now in general use produce and deposit on the warp threads.

In my drawing, I have illustrated my de vice applied to an old, worn structure. In Fig. 2 I have shown by the dotted line 11 and by the full line 11 in Fig. 1 the bearing as worn by the rock-shaft 5. In these views, I have shown this wear to have taken place in the rearmost notch of the series, but it will be understood that it takes place in whatever notch is used, it being of course the custom to journal the rock-shaft in any one of the notches which may be suitable for the particular cloth being woven. When one of these worn brackets is to be utilized to carry out my invention, I remove the fins 12 Wl11Cl1 separate the notches, the milling out extending down to the dotted line 13, shown in Fig. 2. This gives me a very deslrablebracket 14 for the reception of my wood our nal-block 8, since it has an upstanding 11p 15 at each end, between which lips the block 8 is fitted, so that the block will be solidly located on the bracket when drawn down on the milled surface 13 by the aforesaid screw 10, the ends of the block fitting against the upstanding lips 15. In this Way, I can by a very simple operation on the journal-bracket save the same from going to the junk pile. I can also utilize the old worn rock-shaft 5 by simply turning it half around in the arms 6 (set-screws 16 permltting this to be done readily), so as to bring its worn part, shown at 17 in Fig. 1, to the upper side. In this way, I not only completely utilize the old journal bracket and the old rock-shaft, but I produce a bearing for the rock-shaft which is vastly superior to the old bearing in every respect, particularly in that it practically eliminates wear and entirely eliminates the production of the oily particles which fall upon the weft threads and make second quality cloth out of what should be first quality cloth.

The nature and scope of the invention having been thus indicated and its preferred embodiment having been specifically described, what is claimed as new is:

1. In a whip-roll structure for looms, a rock-shaft carrying the whip-roll-arms, a stationary journal-bracket adapted for attachment to the frame of the loom, and an oil-impregnated wood journal-block mounted on the same having a bearing for said rock-shaft.

2. In a whip-roll structure for looms, a rock-shaft carrying the whip-roll-arms, a stationary journal-bracket adapted for attachment to the frame of the loom, and an oil-impregnated wood journal-block mounted on the same having a bearing for said rock-shaft, said bearing consisting of a hole extending horizontally through the block.

3. In a whip-roll structure for looms, a rock-shaft carryin' the whip-roll-arms, a stationary journaliracket adapted for attachment to the frame of the loom, and an oil-impregnated wood journal-block mounted on the same having a bearing for said rock-shaft, said bearing consisting of a hole extending horizontally through the block said block being removably fastened to the bracket by a removable screw extending up through the bracket and into the block.

4. In a whip-roll structure, a stationary journal-bracket adapted for attachment to the frame of the loom having a horizontal plate and upstanding lips at its ends, a Wooden block fitting down on said plate between said upstanding lips, means for fas tening the block down on the plate and between the upstanding lips, said block being provided with a journal hole closed except at its ends, and a rock-shaft extending through said hole and carrying the whiproll-arms.

In testimony whereof I hereunto afiix my signature.
